A method was developed for synthesis of the four stereoisomeric enantiomerically pure 5'-nor carbocyclic nucleosides 4b, ent-4b, 10 and ent-10 starting from the common enantiomerically pure allylic monoacetate 1. Nucleoside analogues were converted to the corresponding triphosphate derivatives 6, ent-6, 12, and ent-12. The substrate properties of the latters towards different DNA polymerases were evaluated.
